Figure 9-1 Continued.Figure 9-1TM 5611532314(2) Inspect stator housing for cracks, distor-tion, damaged threads, elongated holes, a wornbearing seat, and other damage.(3) Inspect the installed stators for signs ofburning, overheating, broken insulation and otherdamage.(4) Inspect the positive and negative heatsinks for cracks, burned areas, and other damage.(5) Inspect the DC unit alternator rotor for ascored or burned bearing seat, for distortion, andother damage.(6) Inspect the bearing for signs of heat,rough spots when burned, fatigue or chipping, andother damage.(7) Replace all defective parts.d. Assembly. Refer to figure 9-2 and assemblethe generator.e. Installation.(1) Refer to figure 6-5 and install the genera-tor adapter on the engine.(2) Position the generator rotor (27, fig. 9-2)on the crankshaft of the engine.(3) Refer to figure 6-4 and install the genera-tor stator housing.(4) Refer to figure 6-3 and install the genera-tor fan.(5) Install the generator end cover.(6) Install the fuel tank and bracket (para 4-22 and 4-23).(7) Install the control box (para 6-3).f. Test.(1) Start the generator set and allow it towarm up.(2) Observe the voltmeter on the front of thecontrol box. If the exciter or stator is defectivethere will be no voltage reading on the set voltme-ter.(3) If no voltage appears on the set voltmeter,stop the set and disconnect terminals 3, 4, 5, and 6at voltage regulator. With a multimeter, measureresistance across disconnected leads F1 and F2(wires from terminals 5 and 6 of voltage regulator)to exciter, and leads T1 and T2 (wires from termi-nals 3 and 4 of voltage regulator) to stator. Theseresistances should be 215 ohms ± 10% and 8.2ohms ± 10%, respectively.(4) If resistance readings do not meet specifi-cations, replace the stator. If resistance readingsare as prescribed, replace the rotor.93
